CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 250,196, dated November 29, 1881.

' Application filed May 23, 1881. (No model.)

and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,which form apart of this specification, and in which- Figure 1. is a front elevation or face view. Fig. 2 is an end view. Fig. 3 is a perspective detail view of the roller-carryin g slide with its appurtenances. Fig. 4 is a detail view of the shade'roller ratchet and its gravitating pawl. Fig. 5 is a detail view of one of the bearings or fixtures for theupper roller; and Fig. 6 is a similar view of the plate for attaching the lower end of each of the guide wires to the sides of the window-casin g.

Similar letters of reference indicate corresponding parts in all the figures.

Myinvention has relation to adjustable window shades or blinds; and it consists in the construction and combination of fixtures, as hereinafter more fully set forth, and particularly pointed out in the claim.

In the annexed drawings, A represents the window-casing, at the top of which is hung a roller,B,between bearings O 0, each of which is cast or made with a projecting lip or lug, at, having a notch, a. Roller B may be operated by means of a cord, 1), secured in and wound around one end of the roller, in a manner well understood. This cord passes down through a staple or keeper, b, and through the slot 0 in a bent plate or arm, E, affixed in one side of thewindow-casin g. This plate has a wedgeshaped notch, d, in one edge, into which the lower endof the cord maybe jammed, and thus fastened, in a simple and expeditious manner, at any desired point.

F F are the guide wires for the adjustable shade-roller G. This roller is hung between brackets or fixtures H H, which are secured upon opposite ends of a bar, I, havinga notch or slot, 1', at each end'for the passage of the guide-wires F, the upper end of each of which is fastened inits appropriate plate 0 and passed over the notched lip a, while its lower end is in like manner passed over the notched lip] of the lower fastening-plates F. The notched lips a and f of plates 0 and F respectively, serve to keep the wires F out the proper distance from the window-casing to allow for the easy play up or down of the bar I with the shade-roller and shade attached to it.

To opposite ends of the bar I are attached cords L L, the upper ends of which are fastened in and wound around roller B. It follows that by operating the cord D-i. 6., pulling it up or down-roller B may be rotated, so as to raise or lower the shaderoller with its appurtenances, which may be secured in any given position upon the guide-wires F by fastening cord D upon plate E in the manner described.

The shade-roller G is rotated by a cord, M, wound around a small pulley at one end. This cord is inserted through the slot n at the outer end of a curved arm, N, which has its fulcrum at h in the bracketplate H. Arm N forms a pawl, the lip m of which engages with aspurwheel or ratchetwheel, 0, secured upon the outer end of roller G. The weight of the curved and slotted pawl-arm N will cause its lip m to engage with the ratchet wheel and keep the roller from turning; but when the cord M is pulled slightly outward, or in a direction from the window, lip m will be released from the ratchet, and the shade P will be lowered by its own gravity. By letting go of cord M the pawl will immediately-drop back into its position to interlock with the ratchet-wheel, and further unrolling of the shade will be arrested.

It will be seen that the shade may be let down any desired distance from the top of the window, so as to provide for ventilation and light from the top without interfering with the position of the shade in the lower part of the window. This adjustment, as well as that of the shade proper, is easily effected, and the operative fixtures are so simple in their construction and combination as to avoid all liability of their getting out of order.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The combination of.the roller B, journaled in fixed bearings, made with the notched lips a, cords D L L, guide wires F F, secured at theirlowerendsin theplates F,having notched my own I have hereto affixed my signature in lipsf, and slide bar I, slotted at 'i i and propresence of two witnesses. vided with the bracket plates H H, pivoted pawl N m, slot-ted at its lower end, and shade- WILLIAM BOWYER' 5 roller G, provided with the cord M, and ratch- Witnesses:

In testimony that I claim the foregoing as JAs. W. GOULTER.
